Can’t keep lavender from dying.

Question

Top dries out but dirt is damp.

Answer 1

You didn't mention whether the lavender is potted or in the ground. Lavender doesn't like a lot of water, and it appreciates poor soil, so feeding it should only take place occasionally. You may be overwatering if your soil is staying damp. If you have it in a pot, the soil might not have enough drainage. Use a sandy, alkaline, well-draining mix. Also, the pot should have plenty of drainage holes.
